Referring nowmore particularly to the accompanying drawings, the numeral 'l indicates a circular drum which is preferably pressed from steel and is formed axiallythereof with a hollow hub 2' which is adapted to receive the outer end 15 portionof an axle therein. The hub is provided atropposite sides thereof with guide slots or grooves. 3, which are provided with flared mouths 4' and are directed obliquely near the side. of the drum, as indicated at 5, the slots 20 terminating in relatively close spaced relation togthe drum Formed on the drum are radially extending spokes B. which serve to brace a circular rim-,1 which is formed on the hub at its The rim section 25 isprovidedwith a bead 8and a shoulder 9. Formedin theencl wall In of. the drum in circumfeliential: ispacedarelation are bayonet openings I:l.: Each of these. openings is located substantially medially. offthe radius of the drum. The; circular wall I2 of thedrum is adapted for engagement bythe usual brake mechanism employed on ,motor, vehicles. j

;-,Assoc iated withthe drum and rim portion is a wheelsection which; is indicated in general by then-numeral; 13, The wheel section comprises a; drop-,center: I4, which is connected with ahub housing. I55. by means of spokes l6. The outenedge f; the rim; isprovided with a bead I1 andtheinner edge thereof is adapted to fit snugly over the shoulder ll It will be understood that, v as seen'in fi r lflof the drawings, the tire is effectually. clamped between the beads B and I1 wheiil thefdevice is completely assembled.

,Ajsibe st seen in Figure 1 of the drawings, the

hub. Formed on" thefhousing at the inner end of thehub flange [8 are guide studs l9, seen more clearlyin Figure '4 of the drawings, which enter and cooperate with'the' guide slots 3 so that when the housing isbeing placed upon the drum;

the bolts, tube-hereinafter described, will be ef- 5 5 a crank, such as indicated at 39.

fectually guided into the openings II in the wall I6 of the drum. Rotatable upon the hub flange l8, within the housing, is a double gear having a central hollow sleeve 2| and teeth 22 at the base thereof. The gear is provided with an outer toothed section 23 which extends throughout the major portion of the diameter of the housing. Mounted within the housing are locking bolts 24, preferably four in number. These locking bolts are provided with circular heads 25 and are threaded throughout their length, as shown at 26. Nuts 2'! are secured on the inner ends of the bolts by set screws or other suitable means. As best seen in Figures 1 and 3 of the drawings, the bolts are adapted to be alined with the lateral portions of the bayonet openings II in the drum I. Rot-atable on each of the bolts is a gear 28 meshing with the teeth 22 of thedouble gear. The gears 28 are rotatable against the inner wall of the housing and are held in position thereagainst by means of locking covers 29 which are provided with sleeves 30, which sleeves are square in cross section to accommodate the squared nuts 2'! therein. The locking covers are, of course, anchored against movement so that rotation of the gears 28 will cause longitudinal shifting movement of the bolts 24, in view of the fact that said gears are threaded upon the threaded portions 26 of said bolts.

Secured to the inner face of the hub housing l5 and adapted for disposal in the path of the bayonet openings 1 I and receiving the bolts 24 therethrough, is a circular gasket or washer 3| which is adapted to provide a tight liquid seal between the two sections of the device so that grease, which is to be packed within the hub housing, will be prevented from escaping into the brake drum and interfering with the proper operation of the brakes. The circular gasket or washer is secured to the face of the hub housing by means of screws 32.

Mounted on the circular wall 33 of the hub housing, at a point on its circumference and near its outer edge, is gear rotating mechanism which ,is indicated in general by the numeral 34. The

gear rotating mechanism, as best seen in Figures 1 and 5 of the drawings, comprises a spur gear 35 which meshes with the teeth of the outer section 23 of the double gear. The gear 35 is secured on a shaft 36 which is journaled in a bearing 31 mounted on the circular wall 33. The shaft is adapted to project outwardly past the circular wall 33 and is formed with a squared socket 38 which is adapted to removably receive Mounted on the circular wall 33 of the hub housing in a diametric plane, is a lock housing 40 and carried in the lock housing is a plunger 4| having a tooth 42 thereon which is adapted to engage between adjacent teeth on the gear 35 for locking said gear against rotation. The plunger is normally urged against the gear by means of a spring 43 disposed within the housing around the stem 44 of the plunger between a flange I44 on the stem and a gasket 244 at the outer end of the housing, and the outer end of the stem is provided with a handle 45 for manual manipulation. When it is desired to rotate the gear, the handle is shifted away from the rim and rotated freeing the tooth to provide additional weight to counterbalance" the weight of the gear rotating mechanism, so that the wheel will be evenly balanced.

Closing the outer end of the hub housing is a closure plate 46 which is provided with an inwardly directed overhanging flange 4'! adapted to overlie the margin of the housing and prevent entry of moisture therein. The closure plate is secured to the housing by means of screws 48. Formed axially of the closure plate is a centering stud 49 which is adapted to be received in an axial socket formed in the closed end 50 of the double gear so that wobbling of the same will be prevented. The closure plate 46 receives the outer end of the shaft 36 therethrough and provides journaling means therefor, a bushing 46l being employed for protecting and journaling the outer end of the shaft 36 of the gear rotating mechanism.

In Figure 1 of the drawings, the device is shown in completely assembled position with a tire 5| on the rim I4 and clamped thereon by and between the beads 8 and I1. The tube 52 within the tire is provided with a valve stem 53 which is necessarily elongated and bent to a slightly acute angle to project outwardly so that access may be readily had thereto when it is desired to introduce air into the tube. When it is desired to remove the tire from the rim, the crank 39 is first inserted into the socket 38 and said crank is rotated, after shifting and rotating the handle 45 and freeing the tooth of the head 42 from the teeth of the gear 35, for rotating the double gear, and, in turn, rotating the gears 28 which are screwed upon the threaded portions 26 of the bolts 24. As said gears are locked against longitudinal movement, the bolts will be shifted inwardly for freeing the heads thereof from the bayonet openings H in the forward wall ll] of the drum. It will be seen that the nuts 27, which are slidable in the sleeves 36, provide guiding means which serve to guide the bolts in their longitudinal travel. It will, therefore, be understood that the wheel section may be readily removed from the drum and the tire removed therefrom with the utmost facility. When the tire has been repaired or changed it is only necessary to reverse the operation above outlined, whereupon the wheel will be firmly and efiectually mounted upon the drum. Attention is directed to the fact that the entire removal of the wheel section can be effected by a single operation. If desired, a crank of the type in Fig. 7 and identified by the numeral may be substituted from the crank 39.

To guard against removal of the wheel by unauthorized persons, a lock is provided at the outer end of the housing 40. As shownin Fig. 8, the end or the housing is made thick enough to receive and enclose a tube 6|, bosses 62 being formed on the housing to enclose and support the ends of the tube. A passage is, of course, formed through the housing to accommodate the tube and, as shown in Figs. 8 and 9, said passage is arranged at a right angle to the bore in which the plunger stem 44 slides and intersects said bore. .The tube is provided at one end with an internal flange 63 and an external flange 64,, the. latter being secured to the housing 46 to retain the tube therein and being provided with spaced spurs 65 to seat in recesses in the housing and thereby insure the proper placing of the tube. The flange 63 serves to retain a bolt 66 within the tube, inwardly directed lugs 61, at the opposite end of the tube, cooperating with the flange to prevent endwise movement of the bolt. Outwardly di- 5";

rected. lugs 68, at the last-mentioned end of the tube, bear against the housing to resist endwise movement of the tube; Itwill be understood that the tube. is of sheet metal and the lugs may be formed by slitting the endof the tube to produce tongues and then bending the'alternate tongues in opposite directions. The stem 44 is provided with a notch 69 in one sideto be engaged by the bolt 66 so that the plunger cannot be withdrawn to permit actuation of the pinion 35 until and unless it is free of the bolt. The tube is formed with a notch in one side to accommodate the plungerstem 44 and its opposite side is longitudinally slitted and equipped with a spring tongue 10. The bolt has a-key-receiving longitudinal channel I I intercepted midway its ends by a notch 12 to accommodate the stem 44 when the latter is released. Diametrically spaced from the channel H a short groove 13 is formed in the surface of the bolt.

The plunger is shown locked in Figs. 8 and 9 in which figures a portion of the bolt is seen seated in the notch in the plunger, the spring tongue H1 engaging in the channel H. When the key is inserted, it will ride on the tongue and push it from the channel so that the bolt may then turn. The key and bolt are then turned through onehalf a revolution so that the notch 12 will be presented to the plunger and the spring will seat in the groove 13. When the plunger is to be again locked in engagement with the pinion. 35, the key and the bolt are turned to the locked position thereby restoring the relation shown in Figs. 8 and 9. The spring tongue 10 is preferably beveled on its side edges in order that, while it will effectually hold the bolt in the position to which it has been turned, release of the tongue from the groove 13 will be easily effected when turning pressure is applied to the bolt through the key.
